CHARLES G. PATTERSON, OF TORONTO, ONTARIO, CANADA, ASSIG-NOR, BY MESNE AS- SIGNMENTS, TO THE NATIONAL ADVERTOGRAPH COMPANY, LIMITED, OF TORONTO,

CANADA, A CORPORATION OF ONTARIO.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed March 28, 1912, Serial No. 686,745. Renewed August 29, 1913. Serial No. 787,397.

To ail whom it may concern Be it known that I, CHARLES G. Paranasox, subject of the King of England, and resident of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have made certain new and useful Improvements in Automatic Label- Printers; and I hereby declare that the following is a full, clear, and exact description of the same.

In my concurrent application, Serial #678,157, for automatic label printers, filed January 24th, 1912, I have shown and described a printing attachment for wrapping paper and the like. which will automatically print the paper when being unwound from the paper roll, and follow by gravitation the decreasing diameter of the paper roll as the paper is unwound therefrom, this being accomplished by mounting the printing roll in an arm pivoted to a stationary support, so that the printin roll can move radially with respect to its pivotal connection with the support and remain continually in contact with the paper roll.

The printing roll, when in contact with the paper roll, when the latter has been evenly and smoothly wound, makes a clear imprint of the type thereon, and satisfactorily performs its functions to meet the mostexaeting requirements, but when the paper roll is not evenly and smoothly wound, as it sometimes happens, the type carried by the printing roll makes an imprint only where it comes into contact with the surface of the paper roll, and then the impression of the type on the paper is not always as clear as it should be.

One of the objects of my invention is to insure the printing roll automatically adapting itself to any unevenness in the surface of the paper roll whereby the wholecf the type will be continually in contact with the paper, regardless of any reasonable or ordinary unevenncss of its surface.

In my said concurrent application, the type for printing the label is permanently attached to the printing roll, and in the apparatus forming the subject matter of my said invention, I have made 'no provision for interchanging the type so that the reading matter of the label can be changed from time to time to meet the different trade requirements.

A further object of my invention, is therefore, to provide the printing roll with means whereby the type can be assembled in groups and each assembled group of type can be attached to or detached from the printing roll independently of any other group or groups.

For an understanding of my invention, reference is to be had to the following description and to the accompanying draW- ings, in which Figure 1, is a side elevation showing the printing attachment in contact with a roll of paper; Fig. 2, is a rear elevation of the printing attachment and support; and, Fig. 3, is a section on the line a-a Fig. 2.

Like characters of reference refer to like parts throughout the specification and drawings.

The roll of paper a has a core I) journaled in the standards 0 of a suitable framework (Z. Attached to the framework (Z, is the support a to which is pivoted an arm f, having a swivel connection It with the arm 9, in which is journaled the printing roll 7'. The arm f, by means of its pivotal connection 2' with the support a, can swing radially to maintain the printing roll j in contact with the paper roll a, and the arm 9, by means of its swivel connection 71 with the arm f, will permit the printing roll 7' to automatically adjust itself lengthwise to the surface of the paper roll a.

To insure the adjustment of the printing roll 7' to the surface of the paper roll a, I insert at each end of the printing roll a plate 7c of lead or other heavy material, the weight of which causes the printing roll to press against the paper roll, and insures the print ing roll instantly adapting itself to the surface of the paper roll.

The paper a is unwound from the paper roll as indicated in Fig. 1 of the drawings, and is usually drawn away quickly when required for wrapping purposes. As this causes the rapid revolution of the paper roll a, and consequently the more rapid revolution of the printing roll y, it is necessary to so construct the printing appliance that it will automatically adapt itself instantaneously to the surface of the printing roll, and I find that the means above described enable itto satisfactorily perform this func tion.

In Fig. 2, I have shown the printing roll to be provided with three groups m, m and m of type, each group being separately attached to the printing roll. The two groups m, m, as shown in Fig. 2, are permanently secured to the printing roll, while the middle group m is detachably connected to it, To detachably connect the middle group m to the printing roll, I attach to the surface of the printing roll, two clamps p, and attach the type to a flexible metal plate 0 and provide the ends of this plate with projecting tongues 0 which enter between the clamps p and the surface of the printing roll The flexibility of this metal plate 0 permits the tongues 0 being readily removed from or inserted between the clamps p and printing roll y'.

As the group of type m may carry the merchants name and address, and the group of type m may carry any fixed advertising matter which the merchant desires to use, it is consequently not necessary to make these two groups detachable, but it is possible to do so by using the same means as for the group we. The group m may advertise one class of goods or some special line which the merchant desires to bring to the attem tion of his customers, and by having this group interchangeable, it is possible to ad vertise any number of special lines and to change the advertising matter at will.

Having thus fully described the nature of my invention, what I claim as new and desire to secure by Letters Patent is A printing device for paper roll holders consisting of a base, said base mounted at a suitable distance from and independent of a paper roll holder and paper roll, a standard pivotally connected thereto, an arm pivotally connected to said standard, said arm forked at its one end, a printing roll mounted in suitable journals in said arm forks, an inking roll, and a distributory roll suitably mounted beneath said printing roll and resiliently held in contact therewith and with each other.
